Please help...Injector issue

I have a 97 TJ 2.5 auto. I just did radiator, exhaust manifold, trans cooling lines and oil pan gasket. Drove it about 100 miles and then a 1000 yards from my house it just died. Had it towed because it was all up hill (of course it would be up hill!). Checked all my plugs and fuses they are good. I can hear the fuel pump turn on. The fuel rail is getting fuel. I am getting the P0201 and P0202 injector one and two codes. Don't know what to do from here. Any help would be great. I am supposed to be leaving for Rausch Creek me t Friday so I have little time!?

PLEASE HELP!

Was it running ok before this happened?
Did it start and run correctly those 100 miles?
Is it getting spark?
Will it run or attempt to if you spray a bit of starting fluid in the intake?
When it died did it just shut off and not start again?

Ran like a champ. Didn't think to check for spark. Will do that after work. No starting with starter fluid. And she just died in the middle of the road.

Crank sensor unplugged ? or ng

Gonna have to wait till tomorrow morning to check. How can one tell if the CPS is bad? Would that make the injector codes come up?

Generally speaking, no, injector codes and bad CPS dont go hand in hand, that being said it is a jeep, so anything is possible:P . Start by check your injectors first just for the to be sure, you can use either a 9v battery or the 12v car battery, take 2 wires and use them to energize the injectors. first injector 1 then injector 2. you should hear an audible click from the injector when power goes to it. dont worry about which side is - and which is +, if i remember correctly it will click either way or it will only click when you get the right pols, but i can tell you for sure you wont ruin the injector by mixing up the +/-. you can also use a small flashlight bulb to check to see if power is going to the injector by jumping terminals to the bulb. if the bulb flashes than you are getting power. If both click and are getting power than I would move on to checking for spark from your ignition coil, then your distributor, then your plugs. but if your getting injector codes i would start with the injectors. It is entirely possible that your ECU may have given up the ghost. In my experiences if power is going to the injectors and the injectors work, 9 times out of 10 there is a problem with the ECU.

Does it have spark????
Check for spark first, it is easiest thing to do and if you have it you can rule that out.

For all you know,, you could have set those codes after initial start up after you worked on it .
They could be erroneous codes, you may have set them and they mean nothing.
 


,,ASD relay controls injectors,,
,,,Check fuse no.6 30amp and test for power at B1 and B3 at ASD relay.

So now that I played with it a little. I totally missed looking at one of the fuses. It was F21. From what I read it is for the injectors. Not sure what would cause that to blow though. Anyone have any thoughts on what it is. For now I will grab an extra or two and stay local.

Thank you all for your help and input. Rausch Creek here I come!
